Thanks everyone. I've just gotten curious about this: are the AI 2 amas large enough to use them in a small, one person catamaran? I'm going strap a couple together to try to rig up a simple flotation test of that idea and check it out before it gets too cold here in the northeast.

If the combined buoyancy of the AI 2 floats is 525 lbs about (240kg), then by the time I got 200lbs of me, and say 75lbs of lightly built structure and rig, that would leave 250lbs or roughly half the amas out of the water. That might work. Certainly the TI amas would. At maybe 660lbs buoyancy, that leaves them riding pretty high.

Aside from like to explore and tinker, I have reasons for looking at this, which I may share after I get my problem with posting pictures solved.
